Title
(EN) CONTROLLER OF INTERNAL COMBUSTION ENGINE

Abstract
(EN) A controller for internal combustion engine in which undue reaction of a throttle valve is prevented when the opening of the throttle valve is controlled based on a plurality of request torques. The controller for an internal combustion engine comprises a means for gathering the request torques from a plurality of request torque output means and then calculating a request torque, a first torque control means for making the actual torque follow up the variation in gathered request torque by varying the opening of the throttle valve depending on the variation in gathered request torque when the sensitivity of opening variation of the throttle valve for torque variation is small, and a second torque control means for making the actual torque follow up the variation in gathered request torque by fixing the opening of the throttle valve and varying the operating amount of an actuator other than the throttle valve depending on the variation in gathered request torque when the sensitivity is large.
(FR) Cette invention concerne un dispositif de commande pour moteur à combustion interne, dans lequel la réaction injustifiée d'un volet des gaz est empêchée quand l'ouverture du volet des gaz est commandée sur la base d'une pluralité de couples requis. Le dispositif de commande de moteur à combustion interne comprend des moyens conçus pour totaliser des couples requis depuis une pluralité de moyens de sortie de couple requis, et calculer ensuite un couple requis. Ledit dispositif commande comprend en outre de premiers moyens de régulation de couple destinés à forcer le couple réel à suivre la variation en couple requis total en faisant varier l'ouverture du volet des gaz en fonction de la variation du couple requis total quand la sensibilité de la variation de l'ouverture du volet des gaz pour la variation du couple est réduite. Le dispositif de commande comprend enfin de seconds moyens de régulation de couple destinés à forcer le couple réel à suivre la variation en couple requis total en fixant l'ouverture du volet des gaz et en faisant varier la mesure d'actionnement d'un actionneur autre que le volet des gaz en fonction de la variation en couple requis total quand la sensibilité est grande.
(JA)  本発明は、内燃機関の制御装置に関し、複数の要求トルクに基づいてスロットルバルブの開度を制御する場合に、スロットルバルブの過大な反応を防止することを目的とする。  本発明の内燃機関の制御装置は、複数の要求トルク出力手段からの要求トルクを集約した集約後要求トルクを算出する要求トルク集約手段と、トルク変化に対するスロットルバルブの開度変化の感度が小さい場合に集約後要求トルクの変化に応じてスロットルバルブの開度を変化させることによって実トルクを集約後要求トルクの変化に追従させる第1のトルク制御手段と、上記感度が大きい場合にスロットルバルブの開度を固定するとともに集約後要求トルクの変化に応じてスロットルバルブ以外のアクチュエータの動作量を変化させることによって実トルクを集約後要求トルクの変化に追従させる第2のトルク制御手段とを備える。
